Umm... what bike it is an important thing to know, but as I've already said (in another thread!), a 350 lbs spring would suit you good.

how could a 350 spring fit me??

what do i mean?

the 300 spring gives me about 35% sag, with no preload. so with a little preload, i get about 33-34% sag, which is pefect for freeride/dh.

a 350 spring provides 30% sag, so i will never reach the desired 33-34%...

a 400 spring...well, it's out of the question...

so you rely on some modeling program instead of real life experience.

steel springs can be had for like $10-30each. buy a 300, 350, and 400. dont rely solely on sag, especially trying to nitpick over 2-3% on a spring calculator. people look at sag % far too much.

also fwiw, those calculators only get you ballpark results, not exact rates. i used one to compare it to my actual sag, and it was off by 50-70lb spring rating.

A friend of me is on Commencal Supreme DH and he weighs 165 lbs and he is on a 350 spring. He just have 27-28% sag, but that's the way he likes it. He runs quite a bit of compression in the shock, but he still bottoms it when he's supposed to. He is a rather aggresive rider.

Stop doing your fancy mathematics and get out and try a spring on your shock in real life.

The spring rates calculators have provided me have been off by quite a bit as well.

Online spring calculators never work for me.

So you're asking what spring to use and then dissagreeing/arguing somebody's opinion? If you know what to use why ask??? Not to mention its pointless to ask without mentioning what frame you're using.

thank you all!

i'll try a 250,300,350 and 400.

 

[staike]

Try the 350 first.

I'm 6'6" (figured height matter since we can go further back on the bike, leverage etc, we have a different set-up ) @ 210 pounds, I'm running a #350 shock spring (-/+ 20% sag) w/ FIRM spring in Boxxers, loving it :thumbsup:
